Let's divide 485702 by 21
Let's see how many times 21 fits into 485702.

Let's proceed to step 1:
4 divided by 21 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 21

Let's proceed to step 2:
21 goes into 48 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 42 from 48 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 21

Let's proceed to step 3:
21 can be fit into 65 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
If we take 63 away from 65, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

Step 4:
21 can be fit into 27 1 times, resulting in a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 231.0
If we take 21 away from 27, we end up with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 21

Step 5:
When dividing 60 by 21, we get 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2312.0
Subtract 42 from 60 to get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 21

Step 6:
The number 21 fits into 182 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 23128.0
Subtracting 168 from 182 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
140 divided by 21 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 23128.6
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
When dividing 140 by 21, we get 6 with a remainder of 14.
The next digit of our result is 6. 
Result so far: 23128.66
Deduct 126 from 140 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 23128.66, and the remainder is 0.014.
